To all whom it may concern: 3

Be it known that I, JULIUSHT. ,SENG, a citizen of the United States,residing at Chi: cago, in the county of Cook and Stateof Illinois, haveinvented a new and useful Improvement in Corner-Locks for Bedsteads, ofwhich the following is a specification.

This invention relates to improvements n corner-locks for bedsteads; andthe princrpal objects in View are to provide a lock of this charactercapable of being readily, economically and conveniently struck-up fromsheet-steel; capable of receiving and rigidly holding the side andend-rails of the bedstead and utilizing the, latter rail as anadditional support for the former; and which will include alocking-means for the side-rails that will permit of a reversal of thesiderails and which is operable, if desired, without the employment oftools,

Other though minor objects of, the invention will hereinafter appear,and the novel features of the invention will be part1cularly pointed outin the claims.

Referring to the draW1ngs Figure 1 is a side elevatlori ofa cornerlockfor bedsteads embodying my inventlon, the same being shown applied to acornerpost of a wooden bedstead, the end-rail be,- ing shown incross-section and the slde-rall in side elevation and broken away;

Fig. 2 shows these parts in vertical CPQSS', section, thesection beingtaken on the' l1ne 2--2 of Fig. 1, and the lock removed from the post; I

Fig. 3 is a vertical longitudinal sectional view taken on the line 3-3of Fig. 2; and,

Figs. 4 and 5 are details in plan of the ends of the side and end-railsrespectively. 7

Similar numerals of reference indicate similar parts in all the figuresof the draw- In S. I

l he lock comprises a box-like socket, the front and bottom of which ispreferably open and the top and rear closed, as shown. It may,therefore, be said preferably to comprise the two vertical side-walls 1,the transverse or top-wall 2, connecting the sldewalls, and which at itsrear may be upwardly bent at a right-angle and perforated, to form theattaching ear 3, and the rear double wall 4. An attaching-screw 5, maybe passed through the perforation of the ear 3 and through similarperforations formed at convenient points in the backand iitilizedfitosecure the socket to i the face, of thebed-post 6. The corner-lockherein illustrated is adapted for use in con nection with a corner-postof a wooden bed, and therefore attachingscrews are employed, but it willbe understood that the invention is applicable to corner locks in tendedfor use in connection with the cornerposts of metal; beds, in whichinstance, the back-wall of the socket may be formed in any of thewell-known conventional ways to effect such an attachment, thefasteningmeans employed for connecting the socket to the corner-postforming no part of my present invention. a j I j The inner wall 1 of;thesocket, near the upper edge or top-wall 2, and at about its transversecenter, may, have punched therefrom, a transversely disposed lug 7 whichleaves in said wall a correspondingly shaped opening 8. The upper edgeof this opening, for apurposeherelnafter apparent, occurs a distancebelow the adjacent surface of the top-wall corresponding to thethickness of the angular side-rail hereinafter referred to. The end orcross-rail 9, is formed of angleiron, as is usual, and comprisesthehorizontal web lOand the vertical web jll. These webs are, of the samewidth, and the vertical web is riveted, as at 12, to the lug or ear 7the opening 8 of the socket and extending transversely therein a shortdistance andimmediately below the underside of the top wall of thesocket; In order that the inner end of the vertical web 11 of the end orcross-rail will not interfere with the adjacent attaching-screw or withthe locking means hereinafter described, said inner end mayberecessedr'or cutout, as at 13;

Immediately, below the underside of the top -wall of the socket,theinner one of the side-walls 1, may be extended horizontally beyond.its companion wall, as at 1e, thus producing upper and lower sidesforming angular stop-shoulders 15. When the rail is in position Withinthe housing with its horizontal flange or web uppermost, it will be seenthat the free edge of the latter abut-s against the inner ;wall of thehousing, so that said inner wall may be said to form an abutmenttherefor. It will be apparent that a complete inner wall, as shown, isunnecessary for ,this purpose and that any other form of abutment willanswer. I When the and wall.

are widened and provided with cam-faces flange is lowermost, it will,underlap the,

lower shoulder 15 and be bound or clamped upwardly thereagainst by thedescribed locking means.

The locking means employed for the siderail preferably comprises twocompanion similarly formed cam-levers 16, mounted and adapted to rocksimultaneously upon a transverse pintle 17, secured to the oppositeside-walls 1, said cam-levers each being located in close relation to aside- At their upper ends these levers 16 18, the highest portions ofwhich are in advance of the pintle 17. A; cross-piece or j bridge 19,serves to connect'the cam-arms V 16, and, for conven ence, the cam-armsand bridge may and preferably are formed of a single piece bent toshape. An opening 20, is formed in, the bridge, preferably at one sideof the center thereof so as not to interfere with the adjacentattaching-screw .5 (shown by dotted lines Fig. In the opening 20, is aloose fitting adjustingscrew 21, the rear end of which may be rounded,as shown, and seated in a countersink 22, formed in the back-wall of thesocket. A 'nut23, (see Fig. 3,) is preferably slightly tapered andthreaded on the screw 21, immediately back of the bridge 19, and, aswill be apparent, by manipulating the adjusting-screw, the cam-leverswill be rocked upon the pintle and held in any of their adjustedpositions, the nut being held against rotation.

The side-rail 24, as usual, is formed of angle-iron, and thereforecomprises the horizont-al web 25' and the vertical web 26, taking theseparts in the positions they are shown in the figures of the drawings.The socket is preferably made slightly narrower than thewebs 25 and 26of the side-rail, so that, invorder for the rail to enter the socket,said webs are slightly reduced transversely, as at 27, at their ends andfor a distance corresponding with the length of the socket, thus leavingthe webs beyond the socket with lateral angular shoulders 28, which,when the side-rail is in position, overlap or underlap as the case maybe, the stop-shoulder 15 adjacent thereto. j

In order to assemble the side-rail with the socket, the adjusting-screw21 is first loosened so as to permit the cams to rock forward asufficient-distance to admit the end of the side-rail. When in position,assu1ning the side rail to be as shown in the figures of the drawings,the upper or horizontal web 25 will approximately fit between the twovertical side-walls of the socket and the squared abutting-end of therail will abut against the back-wall 1 thereof; also the shoulder 28 ofthe web 25, will lie across and be supported by the shoulder 15 of thesocket, the interlocking of these two shoulders serving to resisttorsional strain of the rail. The screw is now run down upon the nut 23,thus forcing the upper ends of the cam-arms rearwardly and causing theouter cam to bind against the under edge of the vertical web of theangle-iron of the siderail and force the latter tightly upward againstthe underside of the top-wall of the socket, whereby, as will beapparent, the side-rail is rigidly and securely locked in position. Forthe purpose of operating the adjusting-screw 21, an ordinary screwdrivermay be used, or in fact, any other object capable of being used as ablade or key, as for instance, an ordinary coin-like a quarter of adollar. To release the side-rail requires but a retrograde movement ofthe screw sufiicient to withdraw the cams from binding position upon therail. As will be apparent, the rail may be reversed from the positionshown in the drawings, that is, with the horizontal web at the undersideand dis posed against the lower shoulder 15 of the socket. In suchposition, the vertical web lies against the adjacent face of the outervertical side-wall and the horizontal web extends across the socket withits edge lying against the inner or adjacent face of the companionside-wall, both cams then be ing in position to bind against theunderside of the horizontal web. Which ever position the side-rail becaused to assume it will be secured against movement by the upwardbinding of the cams thereagainst.

If desired, but one cam-arm may be employed, and such may be located atone side or intermediate the two sideewalls 1 at any point; also anymeans may be employed for operating the camsa simple wedge-key insertedbetween the bridge 19 and the backwall 4: being available for thepurpose.

ll hen the side-rail. is employed in the position in which it is shownin the drawings, that is, with the horizontal web uppermost, it will beseen that the same overlap the inner end of the end-rail, so that thelatter serves as a support for that side of the side-rail and whenreversed, that is, with the web lOWOlD'lOSl), the two cams 1S operate tobind against the same at its underside, the shoulder 28 underlapping theshoulder 15 of the socket. In either position, therefore, of theside-rail, torsional strain is resisted successfully.

It will be observed that the opening 8 in the side-wall 1 of the socketis slightly narrower than the horizontal web 10 of the cross or end-rail9, and that the edge of said horizontal web is notched as at 29. Thisnotch, when the rail is in position, engages positions, I

with the edge of the opening 8, forming an interlocking j oint whichaids in securing the rail rigidly in position. By slightly turning therail when it is entered through the opening 8 and then straightening therail to its proper position, the'interlocking of the parts occur, afterwhiclrthe rail maybe riveted to the-lug or ear 7.

The doubled rear wall, while desirable, is not necessary. It is readilyformed by bending therearportions of the blank forming the sidewallsinwardly at an angle to the remaining portions, that of the oneoverlapping the other. When present considerable additional strength isadded to the socket.

It will be seen that regardless of which of the two positions theside-rail is caused to cocupy, the vertical web thereof will liealongside the adjacent side-wall, the upper edge alongside the top orconnecting-wall and the outer horizontal edge will lie alongside thecompanion side-wall; and therefore, that the rail will have at all timesthree points'of longitudinal contact with the walls of the socket,
